  1. Freeze Flip Sim

    Hey Guys, Imagine an object which fills with liquid over time. When the object is full of liquid i want the motion of the Flip Fluid stop oder decrease over time. For example: - Object fills with Flip Fluid from Frame 1 to Frame 96. - Liquid and all motion of it slows down from Frame 96 to Frame 144, at Frame 144 everything is not moving anymore. I tried some pop wrangle inside my DOP but i cant get this working. Any suggestions? Should i do this after the DOP in SOP Level in a Vop/Wrangle or could I achive this inside my DOP? And How? Thanks and Greets, me
  2. Disable (some) FLIP Particles

    Hey guys, Is there a simple way to disable some particles from the simulation like i'd do with RBD? I have a set of particles inside a group and I need them to be stopped at same position but still interacting with the other particles. Does it makes sense? The group is animated I tried setting v=0 but it doesnt work as expected. I did another trick inside a sop solver to get the position from the previews frame so it stays static but then I cant use the resample. Im just wondering if theres a a simple way like like an attribute the would make them sleep. Cheers, Alvaro
  3. PARTICLES MOTION STOP

    HI, I know this might be an easy thing but i tried out and seems like i'm making a silly mistake. How can i make the movement of particles stop as it slows down?
  4. Hello everyone. I got stuck - anybody knows how can I make the Wiresolver disable the points of the wire when they collide with the ground plane (or anything really ). Just stop solving them so they stop moving. This is a simple scene. There is only a Windforce dop with some noise and downward velocity in Y and the Wiresolver (and ground plane connected to the Static Solver). https://youtu.be/iMRW3GQ-XH8 With pops we have collision behavior but the wires don't work with pop nodes. Is there any built in functionality for this or does it need code? Extra question: When I use gravity and windforce the gravity doesn't work, so I faked it. We cannot mix those forces accepted by Wiresolver with stuff like gravity? I've tried introducing POP forces as well - with POPsolver connected to Multisolver, together with Wiresolver, but the sim just goes crazy. I've attached a test scene (I've also added a box to collide with). fallingWire_Problem.hipnc
  5. RBD Stop Problem (FLIP)

    I'm gettin' this weird problem. Around frame 164 the RBD sphere just stopped (near the very end). I've tried to recreate the scene and the same problem happened, I'd love to understand why. I've noticed that if I increase the AutoDop substeps the rbd stops earlier. Could it be related to cache? I've tried caching it with a file node but it didn't solve the problem. Also, does anybody knows if the ROP Output Driver works on the apprentice version? I've seen someone using it and i've just tried it with no success. I'm with the apprentice, btw. The file is attached in case anyone can have a look Thx, AlvaroBuoancy_v2_.hipnc
  6. How would I simply stop my smoke from emitting completely on a certain frame? I'm using Houdini 13 Thanks
